Study Notes
Introduction
- Active Directory (AD) is a Microsoft network management service used to manage and control network communication.
- A Domain Controller is the central hub for network communication, managing user credentials, computer accounts, security policies, and files.
What is Active Directory?
- A directory service designed by Microsoft for network management.
- It stores and manages network resource information, including user accounts, computers, and group policies.
- It authenticates and authorizes users in a Windows environment.
What is a Domain Controller?
- A computer server that hosts Active Directory and runs the Active Directory Domain Services (AD DS).
- AD DS manages directory data, authentication, and data replication across multiple Domain Controllers.
What does a Domain Controller do?
- It authenticates user credentials and verifies identity.
- Generates a security token allowing access to network resources.
- Shares authentication tokens with other applications, enabling users to access services like email and file sharing.
Benefits of Active Directory
- Centralized Administration: Manages user accounts, computers, applications, and security policies from a single platform.
- Unified Authentication: Simplifies user logins and access controls across the network.
- Resource Management: Allows administrators to inventory and manage network resources.
- Security Policy Enforcement: Implements consistent security policies across the network.
Active Directory Information Categories
- Resources: Network devices like printers, scanners, and network shares.
- Users: Accounts and groups representing users with specific access rights.
- Services or Applications: Examples include email services and authorization servers.
Active Directory Features
- Hierarchical Organization: Manages network resources and security policies through a tree-like structure.
- Centralized and Distributed Database: Network data is centralized for consistent access but can be replicated across multiple Domain Controllers for redundancy and performance.
- Scalability: Efficient data access even in large networks thanks to an advanced indexing system.
- Security: Administrators can manage users and groups with specific rights through access controls.
- Flexibility: Supports the customization of pre-defined objects and the addition of new objects.
- Policy-Based Administration: Allows for the creation of group policies, defining the behavior of users and devices on the network.
Active Directory Structure
- X.500: A standard defining the structure and organization of directory services, establishing the basis for Active Directory's hierarchical structure.
- LDAP (Lightweight Directory Access Protocol): Simplified version of X.500, using TCP/IP, for directory access protocol. Enables integration with other operating systems.
Active Directory Schema
- Physical Structure: Consists of sites, which are physical locations where DCs communicate. A site typically represents an area connected by a LAN. Sites can be connected through WANs across geographical locations.
-
Logical Structure: Organizes network resources based on the organization's structure. Key components include:
- Organizational Units (OUs): Group objects like users and computers within a domain, allowing for efficient management.
